IIT-Guwahati researchers develop low-cost catalyst for cleaner hydrogen production
Scientists at IIT Guwahati have made a special helper that can split water into hydrogen.
Hydrogen is a clean fuel that many people want to use for energy.
When hydrogen is used, the main thing left behind is water.
But today, most hydrogen comes from dirty fossil fuels like natural gas and coal.
Making it that way releases greenhouse gases, which are bad for the planet.
Splitting water needs a helper called a catalyst to work quickly.
The best helpers are very expensive because they use rare metals.
The new catalyst uses cheap nickel instead, so it costs much less.
It uses almost 88 per cent of the electrical energy to split the water, and it stays stable for a long time.
This could help India make cleaner hydrogen for its Green Hydrogen Mission.
Researchers at IIT Guwahati have developed a low-cost catalyst that produces hydrogen from water through electrolysis.
The catalyst uses a nickel salt combined with an anthracene-based organic molecule instead of costly noble metals.
About 88 per cent of the electrical energy supplied was effectively utilised to split water.
Currently, 90–95 per cent of hydrogen is generated from natural gas and coal, releasing greenhouse gases.
The study supports India's National Green Hydrogen Mission and the wider shift towards cleaner energy.
- Who
- Researchers at IIT Guwahati, led by associate professor Akshai Kumar, with assistant professor Kalishankar Bhattacharyya.
- What
- Developed a low-cost nickel-based catalyst that produces hydrogen from water through electrolysis.
- Where
- IIT Guwahati, India.
- When
